CLAUDE S.' BUCHANAN, 0F DAYTON, Oil-HO.

To all whom t may concern:

Be it known that I, CLAUDE; S. BUCHANAN, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful lmprovements in Filling Devices, of which the following is a specification.

'.lhis invention relates in general to tiling devices and more partiel arly to a device for liling cards or inserts in such a manner that they shall be visible and that the cards shall be easily re-arranged or re-elassified.

lt is a purpose of my invention to provide filing devices which shall be composed of a lminimum of exceedingly simple parts, the major portion thereof being readily stamped or shaped out of sheet material.

It is the further purpose of my devices to provide for the insertion or re-arran'gement of said cards or inserts with a minimum of re-arrangement of the remaining cards or inserts. A complete description of my invention will be found in the accompanying drawings and specifications, in which:

Fig. 1 is a front elevation of my device assembled ready for use, while;

Fig. 1a shows sections of a' disassembly of parts of the device given in the ligure above.

Fig. 2 is an enlarged front elevation of the central insert retainer, with portions broken away to show a portion of the back plate, while;

Figure 2a is a section taken on line 22h-2 of Figure 2; y

Figure 3 is a section taken on line 3-3 Figure 1.

Referring to the details in the above ure-s, 1 is the back plate made preferably of sheet metal. At the inner portion of this` sheet metal back plate, the plate has been formed upwards into two retaining grooves, noted as 2 and 2, Fig. 1a. The junction between the two grooves forms an inverted U, slightly exceeding in height above the top surface of the back plate, the thickness of the inserts 6 and 7 At the lateral outer portions of the sheet metal back plate, the plate has been crimped over to form retaining guide-way flanges 3 and 4t, These two guide-way flanges 3 and a are also slightly in excess, in inner U dimension, of the thickness of inserts 6 and 7, Fig. la. The purpose of havin'g these measurements slightly exceed the thickness of the inserts G and 7 will be hereinafter described.

i j FILING DEVICE.

Application filed June 27, 1923. Serial No. 648,052.

Mounted along the center line of thel inverted U, hereinbefore described, is a detachable front plate or central insert retainer 5, shown in Figs. 1, 1a, 2 and 2L respectively. ,Sama composed preferably of sheet metal, is exceedingly simple, being formed of a single metal strip pierced by one or more rivet holes. Recessed rivets 14 are permanently secured to the central insert retainer as shown in Fig. la. Corresponding retainer' rivet holes 15 are provided immediately beneath each retaining rivet 14, in. the inverted Ll section of the sheet metal back plate 1. Fig. 2 showsan enlarged plan view of retaining rivet hole 15. Same has been formed in such a manner as to receive and retain the recessed portion and head of retaining rivet 111, upon side-wise movement after insertion, as shown in Figs, 2 and 2a. The purpose of securely-holding the central insert retainer 5, against the inverted U portion of the sheet metal baelr plate 1. will be hereinafter described.

As shown in Figs. 1 and 8, lower insert retainers 8 and 9 have been provided. at the lower portion of sheet metalback plate 1. Same have been secured by crimping the sheet metal in such a manner that shoulders (El and 9) have been provided for the retention of the lowest inserts (of 6 and 7) of the entire group of inserts, as shown in Figs. 1 and 3.

las shown in Fig. 1, hanging up holes 10 and 11 have been provided at the upper portion of the' sheet metal back plate 1. Same have been provided' as a means of retaining the entire filing device in a vertical or semi-vertical position during all periods of reference.

In Fig. 1, typical cards or inserts 6 and 7 are shown in position. Title cards or inserts 12 and 13 have been so placedk as to indicate the text of the subject matter immediately below. The central insert retainer may or may not have guide lines or markings connecting or relating to the subject matter of the two columns,

From the foregoing my device may be seen to operate as follows: rlhe cards or inserts are maintained as shown in relative positions i on the sheet metal back plate 1, resting upon the lower insert retainers 8 and 9 of the baclr plate 1, and prevented from lateral movement and held from forward movement by the central insert retainer 5 and the guideway flanges-3 and 4- of the back plate 1, Figs.

l and la. The guide-Way flanges 3 and 1,

as well as the inner retaining O'rooves formedA ing rearrangement throughthe movement ofone or more inserts vertically to` any desired position or having" previously removed theY cent al insert retainer 5, by creating insert vacancy thru lateral removal of one or more inserts. In case of ther former rearrange-- ment, title inserts, together with any surplus subject' inserts, are permitted to slip `entirely withoutthe lguide way flanges El and d ofthe tiling device.` New or previously ren'loved insertsare then introduced*laterally into the vacancies heretofore obtained (by vertical or lateral removal). The central insert retainer is then replaced and the entire tiling.

device returned to its reference position. Title-inserts should preferably be inserted at the head of subject matter.

Thus I'have provided a filing device of exceedingly simple operation and design which can be'clieaply andeasily manufactured and operated, and which will provide for the insertion vof acard or insert at. any. given position Withoutfthe removal of and with thel minimum disarrangement of any of the remaining inserts.

I. claim:
